ZWO ASI2600MM Pro P25

The ASI2600MM Pro is a cooled monochrome astronomy camera using the Sony IMX571 sensor. Its 23.5 × 15.7 mm imaging area records 6248 × 4176 pixels with 3.76 µm pixels and a native 16-bit ADC.

Imaging performance

ZWO specifies 73,000 electrons full-well capacity, peak quantum efficiency of 91% and read noise of 1.0–3.3 electrons. The listed capture rate is 14.3 fps advertised maximum; actual transfer speed depends on image size, ADC/output mode and USB connection. Monochrome imaging allows separate luminance, colour and narrowband exposures using suitable external filters.

Cooling and data transfer

Two-stage TEC cooling reduces thermal signal during long exposures. The manufacturer cooling specification is Two-stage TEC; 30–35 °C below ambient, tested at 30 °C ambient. A 512 MB DDR3 buffer and USB 3.0 connection support reliable downloads.

Connections and power

The camera connection is M42 × 0.75, with sensor spacing of 17.5 mm with standard front assembly. The protective window is 60 × 2 mm AR-coated window. Use a 12 V DC, 3–5 A supply with a 5.5 × 2.1 mm centre-positive connector; the recommended battery range is 11–14 V. Include adapters and any filter wheel when calculating telescope backfocus.
